Answer:
b = 21/15
Step-by-step explanation:
0.6+15b+4=25.6
15b + 4.6 = 25.6
15b = 25.6 - 4.6
15b = 21
b = 21/15
Test:
0.6 + 15*21/15 + 4 = 25.6
06 + 21 + 4 = 25.6
I would subtract the 2nd from the first one
so -4x - -2x = -2x
4y - 4y = 0
-20 - -2 = -18
-2x = -18
now I would divide that by -2 to get the value for x
so no we have x = 9
now you just have to substitute that into one of the equations and simplify to get y
-2 X 9 + 4y = -2
-18 + 4y = -2
4y =16
y = 4
'Pi' ( π ) is the ratio of the circumference of a circle to its diameter.
The exact value of 'pi' can't be completely written with numbers, so whenever
we use 'pi', we always use an approximation.
Answer:
x > 9
Step-by-step explanation:
2x - 7 > 11
2x > 18
x > 9
Each can of green beans costs ($3.00/5) = 60¢ at the
village market, and ($6.10/10) = 61¢ at Sam's Club.
If you're watching every penny, then that MIGHT be enough
of a difference to make you decide to buy your beans at the
village market, but not necessarily.
If, say, the village market is farther away from you, or if there are
other things you're going to get from Sam's anyway, then you
should buy your beans there too.
